CAR-COUPLING.

SPECIFICATION Aforming part of Letters Patent No.'517,059, dated March27, 1894.'

Beit known that l, CHARLES W. PATTON, a citizen of the United States,residing at Ohio Falls, in the county of Olark and State of Indiana,have invented a new and useful Oar- Coupling, of which the following isa specilication.

The invention relates to improvements in car couplings. The object ofthe present invention is to 1m prove the construction of carcouplings,and to provide a simple and inexpensive device capable ofholding a coupling pin elevated preparatory to coupling, and ofmaintaining a link in a horizontal position to enable the same toreadily enter the mouth of the drawhead.

A further object of the invention is to enable a coupling pin to bereadily lifted for setting preparatory to coupling from the top andsides of-a car, and to prevent any liability of the coupling pin beinglifted too high and leaving the draw-head.

The invention consists in the construction and novel combination andarrangement of parts hereinafter fully described, illustrated intheaccompanyingdrawings and pointed out in the claims hereto appended.

In the drawings-Figure lis a perspective View of a car couplingconstructed in accordance with this invention and shown applied to acar. Fig. 2 is a central longitudinal sectional view showing thecoupling pin supported preparatory to coupling. Fig. 3 is a similar viewshowing the link heldV in horizontal position preparatory to coupling.Fig. 4 is a detail perspective view of the combined link holder and pinsupport.

Like numerals of reference indicate corresponding parts in all thefigures of the drawings.

1 l designates a draw-head having a coupling pin perforation 2 toreceive a coupling pin 3, and having mounted in its link cavity acombined pin support and link holder 4. The combined pin support andlink holder consists of a plate, which is hinged by a pintle rod 5 atthe top of the draw-head within the link opening or cavity thereof, andwhich inclines downward from front to rear and is depressed and heldagainst upward swinging by a spiral spring 6 disposed on a pintle rodbetween eyes 7 of the plate and engaging the rearface of the latter.Atits center the combined pin support and link holder is provided withan opening 8 to permit the passage of the coupling pin to enablev thesame to engage a link 9, as illustrated in Fig. 3 of the accompanyingdrawings, in which position the combined pin support and link holderengages the upper face of the link to hold the latter in a horizontalposition to direct the same into the mouth of a draw-head. At the bottomof the opening is arranged an upward extending projection or lug 10,which is slightly transversely curved, and which is adapted toA beengaged by the, lower end of the coupling pin to hold the latter in anelevated position preparatory to coupling, as illustrated in Fig. 2 ofthe accompanying drawings; and when cars come together for coupling thelink 9 will strike the combined pin support and link holder and withdrawthe lug 10 from under the coupling pin to cause the latterto fall intoengagement with it. The lower edge or portion adjacent to the edge ofthe combined pin support and link holder is bent slightly horizontallyto enable it to engage the upper face of the link positively.

The coupling pin, which is provided at its upper end with an eye, isconnected by a chain 1l with the upper end of a grooved segment 13,which is mounted upon a shaft l2, journaled transversely of a car 14:,and adapted to be turned from either side thereof for raising thecouping pin for setting. The segment gives a direct upward pull to thecoupling pin; it receives the links of a chain 11 in its grooves; andits ends are adapted to abut against the car to limit its swing. Theupper end of the segment is adapted to strike the top of the car tolimit its upward swing to prevent the coupling pin from being entirelywithdrawn from the draw-head; and its lower end is adapted to restagainst the car when it is swung down.

The rock-shaft l2 is provided at its ends y with handles 15, and one ofits bearings 16 is provided with a notch 17 adapted to be engaged by theadjacent handle when the latter is in a horizontal position, whereby thecoupling pin will be held elevated against coupling. The rock-shaft iscapable of alim- IOO ited horizontal movement to enable its handie toengage lthe bearing 16. When the coupling pin is prevented fromdescending and coupling by reason of the handle of the rockshaftengaging the notch of the bearing, and 1t 1s desired to release thecoupling pin from the top of the car, a chain 18 extends laterally andupwardly from the segment, and is adapted to be pulled to move therock-shaft longitudinally sufficiently to disengage its handle from thebearing 16. The lower end of the chain 1S is secured to an eye 19, which1s arranged on the segment intermediate of the ends thereof, in orderthat the chain 18, which extends to the top of the car, may be employedfor lifting the coupling pin for setting, besides for disengaging thehandle 15 from the bearing 16.

It will be seen that simple, inexpensive means are provided forsupporting the coupling pin preparatory for coupling and for holding thelink in a horizontal position, and that the coupling pin may be readilyoperated from the top and sides of a car.

Changes in the form, proportion, and the minor details of constructionmay be resorted to without departing from the principle or sacrificingany of the advantages of construction.

1. In a car coupling, the combination of a draw-head having a couplingpin perforation, and a combined pin support and link holder arrangedwithin the draw-head and hinged to the top thereof and incliningdownward from front to rear and provided with an opening to receive acoupling pin and having adjacent to the opening a projecting supportadapted to receive the lower end of a coupling pin, substantially asdescribed.

2. In a car coupling, the combination of a draw-head provided with acoupling pin perforation, and a combined pin support and link holderarranged within the draw-head and inclining downward from front to rearand hinged to the top of the draw-head and provided with an opening topermit the passage of a coupling pin and having at the bottom of theopening an upward extending projection, which is transversely curved andwhich is adapted to receive the lower end of a coupling pin forsupporting the same, substantially as described.

3. In a car coupling, the combination of a car, a draw-head having acoupling pin perforation, a coupling pin, a shaft journaled on the carand arranged horizontally and provided at its ends with handles andcapable of alimited longitudinal movement, a bearing 16 receiving therock-shaft and having a notch or shoulder to be engaged by one of thehandles thereof, a segment mounted on the rock-shaft and connected withthe coupling pin, and a chain extending upward and laterally from thesegment to the top of the car to enable the segment to be swung upwardand the shaft to be moved longitudinally, substantially as and for thepurpose described.

In testimony that I claim the foregoing as my own I have hereto axed mysignature in the presence of two witnesses.

CHARLES W. PATTUN.
